Turns out I accidentally wiped my partitions while messing around the Configuration Utility settings. For future reference, do not create new RAID volumes if an acceleration cache seems to stop working.
Thank you for contacting Intel Communities.
I am sorry to hear about this situation regarding the caching configuration you have.
When creating a new RAID yes the information in the disks would be erased since a format would be needed.
While proceeding with this procedure, you get prompt when the information is going to be deleted.
